1. What is the semi-vulcanized layer? (CN layer)
QMH developed semi-vulcanized layer, through vulcanization reaction to achieve strong bonding without grinding. Adhesion reaches the industry leading level with 1. 2 times adhesive performance of the national standard .
2. Advantage of semi-vulcanized layer
Different from ordinary rubber plate, by cold vulcanization with gB cold bonding glue, CN layer is firmly vulcanized on the surface of the pulley and its bonding strength can be ≥12N/mm². The ordinary rubber plate does not have a bonding layer, and the rubber plate needs to be polished.
